We're working on a longform 1080p/23.976 project with heavy effects and have been crashing quite a bit lately.   We end up with the spinning beach ball every time the "Bins and Sequences Memory" hits about 70%.  What makes it even worse is that the memory usage increases by about 20% everytime we open up the audio mixer.  Does this sound normal?  Suggestions?

Have tried uninstalling and reinstalling Avid as well as creating new projects and user settings.

Running:
